There is technically a slower workaround for this but JSPI is coming soon anyway to firefox 153 and safari 27.

It only took a few days to actually get the engine up, the hard parts where most of the effort was spent was squeezing out performance and increasing stability, as well as attempting the JIT.

Firefox was chosen because its single-process support was in a better place than chromium/blink. WebKit is also possible, it was done by a friend of mine earlier https://github.com/theogbob/WebkitWasm

Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly.

Here are a few things you might find interesting:

- This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets.

- There is a novel WASM->JS JIT for experimental site speedup

- This port cost over 25k in opus/fable tokens for debugging and JIT research

This was just a fun experiment to push the boundaries of WebAssembly. For a more usable "browser in browser" experience, we also built https://github.com/HeyPuter/browser.js that eats a bit less RAM.

Switched over to the github pages fallback. Cloudflare pages isn't suitable because the wasm files (100mb+) exceed the 25mb limit. (i could bypass this with service worker jank but that tends to be fragile). Github Pages also isn't suitable because it doesn't have a native way of sending the coi/coep headers that are required for SharedArrayBuffer to be available. Can also bypass that with service worker jank but I would prefer not to
